MACHINE FOR DUMPING MATERIAL.

Specification of Letters Patent.

Patented Jan. in, Tedd.

Application filed January 2, 1913. Serial No. 739,698.

Toall whom 2'25 may concern;

been the common practiceto dump the trays or boards containing the wafersby hand, one tray at a time so that the wafersslide off into a box or bucket. considerable percentage of the wafers is broken, thus entailing a severe loss, and the operation of picking up a tray from one pile of them, dumping it, and then placing it in another pile, consumes a considerable amount of time and consequently is expensive.

The primaryobject of this invention is to provide a means to overcoine'the difiiculties above set forth by providing a device whereby a pile of trays or boardsmay be dumped at a single operation and with an extremely small percentage of breakage of the wafers.

In the accompanying drawings Figure l is a side elevation of an illustrative embodiment of the invention in upright position, Fig. 2 is a longitudinal vertical section of thesame, Fig. 3 is a similar view with the device in dumping position, Fig. f is a hori" zontal section, Fig. 5 is a fragmentary sectional elevation, and Fig. 6 is a fragmentary sectional elevation 'of a truck with a pile of trays thereon.

As illustrated in the drawings the device comprises a holder orjacket composed of a top 10, bottom 12, and sides 14, 16, said holder being providedat its rear with a chamber or extension forming a trough 18' having a rear wall 20, side walls 22, 24, and a bottom wall 25 raisedslightly above the level of the bottom 12. The side walls 22,

24 of the trough extend between the side walls 14, 16 of the holder, and their inner vertical edges 26 act as stops for the trays,

as will be hereinafter explained.

The trough 18 is divided by the shutters In this operation a or partitions 28 into compartments 30. The shutters 28 and the end wall 20 are relatively movable; preferably the shutters are pivotally connected at their inner edges to the side walls 22, 24, and have their outer edges engaged by stops 32 when the device is in upright position, as shown in Fig. 2.

The holder is adapted to receive a truck 34 which carries a pile or stack of trays 36. Each tray comprises a bottom 38 and shallow sides 4E0, the front and rear edges or walls of the tray being omitted, thus pro viding a wide, shallow trough shaped tray. These trays are adapted to carrythin candy waters, or whatever other material is desired to be dumped, and are piled one on top of the other upon the truck, so that when the truck is loaded it will just pass between the side walls 14, 16. The "rear or entering faces of saidtrays being adapted to engage the stops 26 to limit the movement of the load into the holder.

The shutters 28 are located at intervals of four orfive trays and their upper surfaces aresubstantially a continuation of the upper surfaces of the bottoms of the corresponding trays, so that when the wafers are discharged from the traysthey will fall only a short distance before striking a shutter, thus preventing breakage.

The holder for the truck and trays is pivotally supported by a shaft. 42, suitably journaled in uprights 14., 46 of a supporting framework. The shaft42 is provided with a crank48, and a pair of winding drums 50, 52, upon which one end of cables 54L and 56, respectively, is wound. The other ends of saidcables are attached to eye bolts 60 located near the forward edge of the sides of the holder and below the center, said cables passing over pulleys 61 mounted on the uprights 44 and 46. The bottom 12 of the truck holder is let into a shallow pit 62 in the building floor 64 so that the upper surfaces of said bottom and floor are flush, to facilitatept-he movements of the truck with its load to engage a stop 68, whereby the holder is held in upright position, said catch being adapted to be released by a foot-lever70, fulcrumed at 72 and adapted to engage the under side of said catch when its right-hand end, as seen in Fig. 5, is pushed down by the foot of the operator.

A counterweight 7a is connected'to one end of a cable 76 passing over a pulley 78. and attached at its other end to an eye-boltv 80 on the top 10 of the holder. This weight tends normally to tilt the holder with its loaded truck into the position shown in Fig.

3, but is restrained by the catch 66. \Vhen this catch is released and the crank 48- turned to wind up the tables 54; and 56, the holder swings up out of the pit 62 under the combined action of the cables 54:, 56 and.

76, and swings over into the position shown in Fig. 3. During the first portion of the.

I crank 48.

The top of the trough 18 is normally closed by a door or closure 81, hinged at 82, and having an eye-bolt 841- at its other edge connected to one end of a cable 86 passing over a pulleySS mounted in a bracket 90 on the top 10 of the holder. The other end of said cable is connected to a counterweight 92 which is slidable in a chute 94011 the top 10. When the device is in its upright position the door 81 is closed, but as the device is tilted toward the left the weight 92 slides downward to the left in the chute 94, thus opening said door. When the device is tilted sufliciently for the wafers to slide off the trays they fall onto the upper sides of the shutters 28 and against the rear wall 20 of the trough 18. The continued rotation of the device brings the wall 20 to form the bottom of the trough 18, and the shutters 28 swing into vertical position away from the stops 32, thus enabling the wafers, or other material, to slide along the wall 20 and out through the open end of the trough into any suitable receptacle. All of the trays are emptied simultaneously and the mass of wafersfalls such a short distance that there is practically no breakage.

\Vhen it is desired to return the device to normal position the crank is turned toward the right to wind up the cables 54 and 56,

which are now in crossed position. When the center ofv gravity of the device passes to the right of the vertical line through the shaft 42, the cables are paid out and its weight is suiiicient to overcome the counterweight 74, and it returns to normal position.
